While git bisect pointed to your patch and reverting it from the commit seems to resolve the issue at that point, there seems to be some other commit in the 3.14->3.15-rc1 interval that is causing problems as well. Are there any sort of debugging options for mmc that I can use to try to better narrow down whats going wrong? thanks -john -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
